Methods of managing storage of HARQ packets are disclosed. One method includes a wireless device receiving variable length HARQ packets. The wireless device performing an error check on each received variable length HARQ packet, and storing within HARQ memory the HARQ packets that fail the error check. Each failed HARQ packet is stored in the HARQ memory by dividing the HARQ packet into HARQ sub-packets, and storing each HARQ sub-packet. The storage locations and storage order of each of the HARQ sub-packets are recorded for future retrieval.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of managing storage of HARQ packets, comprising: a wireless device receiving variable length HARQ packets; the wireless device performing an error check on each received variable length HARQ packet; and storing within HARQ memory the HARQ packets; wherein storing each HARQ packet comprises; dividing the HARQ packet into HARQ sub-packets; storing each HARQ sub-packet; recording storage locations and storage order of each of the HARQ sub-packets.
2. The method of claim 1 , further comprising the wireless device only storing HARQ packets within the HARQ memory that fail the error check.
3. The method of claim 1 , wherein the error check is performed on each received variable length HARQ packet after combining the received variable length HARQ packet with a previously received variable length HARQ packet having a same channel identification.
4. The method of claim 1 , further comprising accessing HARQ packets stored in the HARQ memory based on the storage locations and the storage order of the HARQ sub-packets.
5. The method of claim 4 , wherein accessing the HARQ packets stored in the HARQ memory further comprises appending corresponding HARQ sub-packets to form HARQ packets as originally stored.
6. The method of claim 1 , wherein the HARQ memory and receiver circuitry are located on a common integrated circuit.
7. The method of claim 1 , wherein the HARQ sub-packets each include a number of bits that corresponds with a predetermined block size of the HARQ memory.
8. The method of claim 1 , wherein the HARQ sub-packets are stored in non-continuous memory block locations of the HARQ memory.
9. The method of claim 1 , wherein the error check is a CRC error check of each of the HARQ packets.
10. The method of claim 1 , wherein the wireless device comprises a subscriber unit that supports a WiMax aggregation mode.
